Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine blade testing devices, specifically a testing device for wind turbine blade production. Background Technology

[0002] Wind turbine blades are the core components of wind turbine units that convert natural wind energy into electrical energy. They are also the main basis for evaluating the design and technical level of wind turbine units. After the wind turbine blades are manufactured, they need to be inspected to ensure that the quality is up to standard. When inspecting the surface smoothness, shape, cracks, scratches, bubbles, etc. of wind turbine blades, industrial camera-assisted visual inspection schemes are often used.

[0003] However, in the existing wind turbine blade production inspection, industrial cameras can only inspect the upper surface of the wind turbine blade at a time. When inspecting the two sides of the wind turbine blade, it is necessary to adjust the inspection equipment or the wind turbine blade multiple times, resulting in low inspection efficiency and cumbersome operation. Therefore, an inspection device for wind turbine blade production is proposed here. Utility Model Content

[0007] Preferably, the lower middle part of the sliding frame is bolted to the upper end of the electric lifting rod, and the lower end of the electric lifting rod is bolted to the upper middle part of the connecting plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] In this embodiment, by Figure 1-4The present invention includes a beam frame 1. A first stepper motor 2 is bolted to the middle of one side wall of the beam frame 1. A first transmission screw 3 is provided at the transmission output end of the first stepper motor 2. The first transmission screw 3 is located in the middle of the beam frame 1. A sliding frame 4 is provided around the first transmission screw 3. An electric lifting rod 5 is provided at the middle of the lower end of the sliding frame 4. A connecting plate 6 is provided at the lower end of the electric lifting rod 5. A connecting frame 7 is bolted to the middle of the lower end of the connecting plate 6. A first industrial camera 8 is bolted to the middle of the lower end of the connecting frame 7. Side plates 9 are provided at the lower part of both ends of the connecting plate 6. A second stepper motor 10 is bolted to the outer wall of the lower end of one of the side plates 9. A second transmission screw 11 is provided at the transmission output end of the second stepper motor 10. The second transmission screw 11 passes through the connecting frame 7. Limiting rings 12 are provided on the second transmission screws 11 located on both sides of the connecting frame 7. Sliding plates 13 are provided around the second transmission screws 11 located between the limiting rings 12 and the side plates 9. A second industrial camera 14 is provided on the lower inner wall of both sliding plates 13.

[0022] In this system, the output end of the first stepper motor 2 is connected to the middle of one end of the first transmission screw 3 via a key. The two ends of the first transmission screw 3 are respectively connected to the middle of the two ends of the beam frame 1 via bearings. The middle of the sliding frame 4 is connected to the first transmission screw 3 via a thread, and the two ends of the sliding frame 4 are slidably connected to the beam frame 1. When the first stepper motor 2 is working, it can drive the first transmission screw 3 to rotate. In this way, the first transmission screw 3 can drive the sliding frame 4 with the assistance of the beam frame 1, so that the sliding frame 4 can move laterally along the first transmission screw 3.

[0023] The lower middle part of the sliding frame 4 is connected to the upper end of the electric lifting rod 5 by bolts, and the lower end of the electric lifting rod 5 is connected to the upper middle part of the connecting plate 6 by bolts. The electric lifting rod 5 can move synchronously with the sliding frame 4. When working, the electric lifting rod 5 can drive the connecting plate 6 and the structure below the connecting plate 6 to rise and fall.

[0024] The upper end of the connecting frame 7 is connected to the middle of the lower end of the connecting plate 6 by bolts, the lower end of the connecting frame 7 is connected to the upper end of the first industrial camera 8 by bolts, the upper end of the side plate 9 is connected to the connecting plate 6 by bolts, and the first industrial camera 8 is connected to the vision system for wind turbine blade detection, and its captured images are fed back to the vision system in real time.

[0025] The second stepper motor 10 is connected to the middle of one end of the second transmission screw 11 by a key. The two ends of the second transmission screw 11 are connected to the two side plates 9 by bearings. The middle of the second transmission screw 11 is connected to the lower part of the connecting frame 7 by a bearing. When the second stepper motor 10 is working, it can drive the second transmission screw 11 to rotate.

[0026] The limiting ring 12 is connected to the second transmission screw 11 by a key, and both sliding plates 13 are connected to the second transmission screw 11 by threads. The threads connecting the two sliding plates 13 to the second transmission screw 11 are in opposite directions. This allows the second transmission screw 11 to drive the two sliding plates 13 to move closer or further apart when it rotates, so that the distance between the two sliding plates 13 can be easily adjusted. The limiting ring 12 can limit the position of the sliding plates 13 to prevent the two sliding plates 13 from getting too close. The upper end of the sliding plate 13 is slidably connected to the lower end of the connecting plate 6. The second industrial camera 14 is connected to the sliding plate 13 by bolts. The second industrial camera 14 is connected to the vision system for wind turbine blade detection, and its captured images are fed back to the vision system in real time.

[0027] Working Principle: The device uses an external power supply and is controlled by an external control device. The first industrial camera 8 and the second industrial camera 14 are both connected to the vision system for wind turbine blade inspection. Their captured images are fed back to the vision system in real time. When using the device to visually inspect wind turbine blades, the blade to be inspected can be placed horizontally below the device using a support frame. When the first stepper motor 2 is working, it drives the first transmission screw 3 to rotate. With the assistance of the beam frame 1, the first transmission screw 3 drives the sliding frame 4, causing the sliding frame 4 to move laterally along the first transmission screw 3. This, in turn, causes the first industrial camera 8 and the second industrial camera 14 to move laterally. When the electric lifting rod 5 is working, it drives the connecting plate 6 and the structure below the connecting plate 6 to rise and fall, thereby causing the first industrial camera 8 and the second industrial camera 14 to rise and fall. This process is used to visually inspect wind turbine blades. When inspecting the wind turbine blades, the height of the second industrial camera 14 needs to be adjusted so that it can capture images of the sides of the blades. The width of the connecting plate 6 needs to be 50cm greater than the width of the wind turbine blades. This allows the distance between the two second industrial cameras 14 to be adjusted in real time by the second stepper motor 10, the second transmission screw 11, and the sliding plate 13 when the device captures images of different positions on the wind turbine blades. This meets the shooting requirements of different widths on different parts of the wind turbine blades. During the shooting process of the second industrial camera 14, the first industrial camera 8 will also capture images of the upper surface of the wind turbine blades simultaneously. In this way, the device can perform visual inspection of the upper surface and both sides of the wind turbine blades in one inspection and feed the captured images back to the visual inspection system so that the system can analyze information such as the surface flatness, shape, cracks, scratches, and bubbles of the wind turbine blades.
